Description

Technical Field

[0001] The utility model relates to an application in vehicle technology, in particular to a driver for opening / closing a vehicle side door, the driver comprising a housing, a motor and an execution component loaded by the motor via a transmission system, and further relates to a vehicle comprising the driver. Background Art

[0002] Today's vehicles are increasingly equipped with comfort functions. For example, in order to facilitate entry into the vehicle and to promote aesthetic and aerodynamic styling, vehicles are not equipped with external door handles, for example. However, it is also conceivable to have external door handles, which only transmit a switch signal to the vehicle door lock for opening. In order to make entry into the vehicle easier, more automated and possible, for example in vehicles without external door handles, so-called opening devices or door movers or door position holders / door openers are used.

[0003] Existing drives for opening / closing vehicle doors have the following disadvantages: external water (e.g., rainwater) may enter the drive housing through a gap between the drive mounting portion and the vehicle door and / or an opening on the drive housing through which an actuator (e.g., a push rod) extends; in addition, the movement stability of the push rod needs to be improved.

[0004] Thus, there remains a need to provide improved drivers. Utility Model Content

[0026] The following describes a driver according to an embodiment of the utility model with reference to the accompanying drawings. In the following description, many specific features are described to enable a person skilled in the art to more fully understand the utility model. However, a person skilled in the art can understand that the implementation of the utility model may not have some of these specific features. In addition, it should be understood that the utility model is not limited to the specific embodiments described.

[0027] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0028] Figure 1 A drive 100 for a vehicle side door according to an embodiment of the present invention is schematically shown.

[0029] like Figure 1 As shown, the driver 100 may include a housing 1 and a driving device 2. An accommodating cavity is formed inside the housing 1. The driving device 2 may be accommodated in the accommodating cavity and may include a driving motor and a transmission mechanism.

[0030] The driver 100 may further include an actuator 4, a first end of which is arranged in the accommodating cavity of the housing 1, and a second end of which extends out of the housing 1. The actuator 4 can be driven by the driving device 2 to perform linear motion, for example, to transmit thrust and / or tension to a component connected to the actuator, thereby driving the component to move.

[0031] As an example, the driver 100 can be used to open / close a vehicle side door, and the actuator 4 can be a rod-shaped member, such as a connecting rod or a push rod. The main body of the driver 100 (including the housing 1 and the driving device 2) can be arranged on the vehicle side door, and the first end of the actuator 4 in the form of a connecting rod or a push rod can be connected to the transmission mechanism of the driving device 2, and the second end can be connected to the A-pillar or B-pillar of the vehicle body by bolts, so that the actuator 4 can transmit the thrust / pull force to the side door to open or close the side door.

[0032] Therefore, in the above example, the actuator 4 can make linear movement between a first position and a second position, wherein, in the first position, the actuator 4 is basically completely retracted into the accommodating cavity of the shell 1, and the vehicle side door is in a closed position; in the second position, the rest of the actuator 4 except the first end is basically completely extended out of the shell 1, and the vehicle side door is in a maximum open position.

[0033] like Figure 2 As shown, the housing 1 may include an opening 3 , through which the second end of the actuator 4 extends out of the housing 1 .

[0034] See also Figures 2 to 4 A cover part 5 may be arranged at the opening 3, and the cover part 5 may surround the actuator 4 in the circumferential direction to close the gap between the edge of the opening 3 and the actuator 4. Thus, the dustproof and waterproof performance of the driver 100 can be improved. Here, "circumferential direction" refers to the direction surrounding the actuator 4, wherein the plane where the "circumferential direction" lies is substantially perpendicular to the length direction of the actuator 4.

[0035] like Figures 3 to 5 As shown preferably, the cover member 5 can be constructed to be recessed toward the inside of the housing 1 and its cross section can change gradually to form a cone, cup or bowl shape, thereby constituting an inner sunken hidden design, which does not occupy additional space and can beautify the appearance of the driver.

[0036] The cover member 5 may be made of a material having elasticity and configured as an integral member. For example, the cover member 5 may be formed by rubber injection molding.

[0037] In addition, the cover part 5 may have an orifice to allow the actuator 4 to pass therethrough. The edge of the orifice may form an interference fit with the actuator 4, so that the cover part 5 substantially and tightly surrounds the periphery of the actuator 4 throughout the entire stroke of the actuator 4, thereby ensuring good waterproof and dustproof performance at any position. In an embodiment in which the cover part 5 is conically or cup-shaped or bowl-shaped, the orifice may be provided at the bottom of the cover part 5. It is conceivable that the recessed portion of the cover part 5 may also be configured in other forms, such as cylindrical or cuboid.

[0038] In order to limit the actuator 4 in the second position, the first end of the actuator 4 may include a limiting structure 6, which may protrude transversely from the longitudinal body of the actuator 4 and form a bending portion relative to the body, such as Figure 5 Here, "longitudinal" refers to the length direction of the actuator 4, and "transverse" refers to the direction transverse to or substantially perpendicular to the length direction.

[0039] The housing 1 may include a mounting plate 7, which is used to mount the driver 100 to a predetermined position. The opening 3 may be provided on the mounting plate 7. The end of the bent portion of the limiting structure 6 can abut against the inner surface of the housing 1, such as the inner surface of the mounting plate 7, to limit the actuator 4, and the inner surface faces the interior of the accommodating cavity of the housing 1.

[0040] exist Figure 3 and Figure 4 In the embodiment shown, the cover part 5 is mounted on the mounting plate 7. Figure 5 In another embodiment shown, the cover member 5 may also be formed integrally with the mounting plate 7 , for example, adhered to the edge of the opening 3 of the mounting plate 7 .

[0041] In this article, the vehicle side door is mentioned as an example, but it is not limited to this; the drive for the vehicle side door also relates to other functions in the vehicle, such as electrically closing the front cover, the rear cover or the sliding door. However, this is also only an example, which does not limit the application field of the drive.

[0042] Those skilled in the art can understand that the embodiments described above are exemplary and can be improved by those skilled in the art. The structures described in the embodiments can be freely combined without causing conflicts in structure or principle.

[0043] After describing the preferred embodiments of the present invention in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the appended claims, and the present invention is not limited to the implementation methods of the exemplary embodiments listed in the specification.
